I found a "nice to read" article on Paul Stamatiou's blog about the basics of using RSS feeds.

"RSS has become a valuable technology for everything from casual web users to webmasters. According to a recent Yahoo survey only 12% of internet users are aware of RSS and a mere 4% have knowingly used RSS. RSS exists as a means to gather and display information quickly and easily. By the end of this article, you should know what RSS is and how to use it to make your life easier."
